Tool names and descriptions exactly as the server reported them on Nov 7, 2026. The maker wrote them, not us; we show them as plain text.
get_supportedThe (x402Version, scheme, network) kinds and extensions this facilitator verifies and settles. Same answer as GET /supported.
get_configEvery settleable asset with its address, decimals, transfer method and EIP-712 domain values, plus the pricing model (gas at cost, plus a fee in basis points on the payment value when the asset has a USD price), the gas fallback and the free-credit allowances. Same answer as GET
get_healthWhether the facilitator behind this host is answering. Same answer as GET /health.
verify_paymentCheck a signed x402 payment against its requirements: signature, amount, balance and simulation. Moves no funds. Same answer as POST /verify, and it spends the same per-IP allowance.
payment_statusWhether a signed payment authorization has been used on chain, for a client whose settle reply was lost. Answers unspent, consumed or expired from the chain (EIP-3009 authorizationState, or the Permit2 nonce bitmap). unspent is not final: the authorization can still be used until

Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 2 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 10 days ago.
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
